SUMMARY
The velocity problem involving John and Derek was solved by establishing their respective distances as functions of time. John travels at a speed of 18 km/hr, starting two hours before Derek, who travels at 72 km/hr. By setting the distance equations equal to each other and solving for time, the meeting point was calculated. The key formula used was V = x/t, allowing for the determination of the distance each traveled before meeting.
